MACHINE FOR SURFACE-FINISHING PAPER.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed February 14, 1907- Serial No. 357,333.

To all whom it may concern.-

Be it known that I, LEON M. YoE'Re,'a citizen of the United States of America, and a resident of South Hadley Falls, in the county of Hampshire and State of Massachusetts, have invented certain new and uses in] Improvements in Machines for Surface- Finishing Paper, of which the following is a full, clear, and exact description.

This invention relates to improvements in machines for surface-finishing paper, and more particularly fine writingpaper, and particularly pertains to improvements in the rind of a machine employing a pair of pressure or squeeze rolls in conjunction with a table and operative for imparting a succession of pressures on a plurality of sheets of paper interleaved with zinc or other metallic plates in conjunction with which are commonly employed sheets of cloth placed against the surface or surfaces of the sheets of paper and between the plates for imparting a cloth-like finish to the paper, and in the machine of the kind to which this invention pertains a follower-bar is provided at one side of the pair of pressure-rolls cgmbined with which is a means of yielding resistanee, so that after the plates and paper therebetween have made a pass in one direction through and beyond the pressure-rolls tlie-followrbar will automatically force the plate-stack back again to the action of the rolls, to which reversed rotation is in proper time imparted.

The object of this invention is to so mount the normally horizontally-guided followerbar as to render it capable of a bodily elevating movement and to provide elevating means therefor, so that at the leasure of the machine-tender the followerar may have a position removed from the path of the late-stack on the table, leavin the latter free to be rolled or slid off from t e rear portion of the table as well as from the front portion after the surface-finishing or plating action to a given plurality of sheets has been accomplished. As a result of the capability for the displacement of the follower-bar, as above referred to, the amount of surfacefinishing work on paper which a machinetender or the machine-tender and his helper may accomplish in a given time is materially.

increased.

The invention consists in the combination with a table and a Ipair of pressure-rolls, having adiacent perip eral portions thereof substantially at the table-level, of a bar or follower at one side of the rolls movable horizontally along the table toward and away from the rolls, a means of yielding resistanceof-parts as hereinafter described in substance and set forth in the claims.

In the accompanying drawings sufficient of an ordinary paper-plating machine is illustrated together with the parts and devices constituting this invention in operative arrangement thereon; and in said drawings, Figure 1 is a plan view. Fig. 2 is a sectional elevation as taken along the length of the machine on line 2 2, Fig. 1, the novel devices being shown as in their workingpositions or relations. Fig. 3 is a view like Fig. 2 with the exception that the new devices are shown as in their moved positions. Fig. 4 is a view of parts in detail hereinafter referred to.

In the drawings, A represents the machineframe, comprising a table B, havinga transverse aperture (1 intermediately thereof and having bed-rollers b b at opposite sides of said aperture, and C and D represent the pressure or squeezing rollers mounted in parallelism at the apertured portion of and above and below the table and having the adj acent peripheral portions thereof at or suitably near the table-level.

The parts above referred to are formed and arranged as usual in paper-plating machines, and it may be added that rotary movements are imparted to the pressure-roller successively and alternately first in the direction of the arrows in Fig. 2 and then in the reverse direction to carry the plate-stack first to the left through and beyond the rollers and then to the right, these operations being repeated as many times as necessary until the paper shall be properly or sufficiently plated or surface-finished.

. I will now describe my improvements.

E E represent oppositely-located guide members pivotally mounted at d and near the ends of such members on the table or machine-frame at one side of the pressure-rolls. These guide members have horizontal guide grooves f along the inner sides thereof in which the suitably-formed end portions of the follower-bar G engage. The followershaft '11, an operating-rod is pivotally conbar G is by the sheave-guided weight 9 maintained yieldingly toward the ressure-rolls, receding therefrom as the stac a; is by the roll forced a 'ainst it horizontally away from the roll an against the resistance of the weights 9. The action of receding of the follower-bar and its returning toward the pressure-rolls is not in itself a new characteristic of the present apparatus.

On opposite standards h h a rock-shaft t is supported in a transverse os1t1on somewhat above the'level of the tab e, and du heated .levers m are affixed on this rock-sha t at opposite sides of the machine. To each lever m a link n is connected, said link being also connected to an intermediate part of the respectively adjacent side member E. To the upstanding arm m also afiixed on the rocknected, the same extending over the pressure-rolls toward the opposite end of the machine. This operating-rod 0 has a catchshoulder or abutment p adjacent an elevated cross-bar g or fixture of the machine-frame.

By drawing the op-erati'ng-rodp forwardly from its normal position (shown 111 Fig. 2) to the position shown in Fig. 3 and permitting the shoulder 11 to engage the cross-bar g, as seen in the latter figure, the opposite side guide members E E will be swung to their elevated ositions and there retained, corres ending y carrying the follower-bar G to tile position above the horizontal path of the plate-stack.

In order to render the movements of the last-mentioned arts conveniently sensitive, the counterweig ts t are provided, the same being suspended on cords, chains, or other flexible connections u, guided over the sheaves v and having connections with upstanding lugs or posts w, formed onor aflixed to the guide members E Flat springs y y are affixed on and forwardly extended toward the pressure-roll from the follower-bar, the same having their extremities depending and return-bent, and these springs serve to hold the edge portions of the plates and material therebetween from separating or cooking up, esplecialliy at times when the roll-pressure 1s on t e mi dle or far-distant portions of the plate.

In the utilization of the present improved machine the skilled operator or machinetender stands at the forward end of the machine and has a helper at the rear 'end of the machine, and from nine to twelve girls are usually employed in making up plate-stacks, some of WhlCll stacks as made up are readily at the hand of the machine-tender, while others are readily at the hand of the helper. The time consumed for removing one comparatively heavy stack fromthe machine and bringin another to the action of the latter relative to the time consumed in the backand-fort runs of the stack between the presl surerolls is proportionately considerable.

Now the machine-tender in addition to controlling the pressure-roll-reverse mechanism (which is not shown or necessary to an understanding of this invention) will at times bring plate-stacks onto the forward ortion of the table and run them between t 1e rolls and he will at times also remove some of the plated stacks at his end of the machine, and the helper will also at times bring stacks onto his end of the machine and also will remove some of the plated stacks. In theutilization of the present im roved machine the skilled op erator or mac 'ne-tender stands at the forward end of the machine and has a helper at the rear end of the machine, and wh le, as heretofore, nine to twelve girls have been usually employed in making up and taking care of finished plate-stacks near the front end of machine only, under the present improvements eighteen to twenty-four girls can be employedhalf thereof near the front end and the others near the rear endwhereby some of the stacks as made up are readily at the hand of the machine-tender, while others are readily at the hand of the helper.

It is of course possible for the machinetender to remove the plated stack at the front end of the machine, or by elevating the follower-bar the machine-tender can run the already-finished stack to the helper for removal at the rear end of the machine, and the hel er can then introduce a fresh stack at his en of the machine. The machine-tender can then lower the follower-bar to position and finish this stack in the regular way, and if at this particular eriod the girls working 'on the machine-ten ers end of the machine require a finished stack to open and to remove therefrom the plated sheets the machine-tender can give it to them and take from them a fresh stack and plate the same, or if at that moment the girls at the helpers end of the machine require a stack the machine-tender, by elevatlng the follower-bar, can run the finished stack back to the helper, for it is to be understood that whenever the operating-rod 0- is brought to the position shown in Fig. 3 it is entirely easy to run the already plated stack offat the rear end of machine, leaving an. opportunity for the helper to introduce a fresh stack at this end.

Thus it becomes apparent that the produc-.
